STP: Cubes vs. Spheres is kind of like a horror game, but instead of hundreds of blood-lusting monsters shambling toward you, it's cubes. Each level consists of a fairly open environment and, like in a nightmare, you can't move. Then cubes start to approach. If three cubes cross into your territory, the game ends. All you have to defend yourself is a supply of spheres that you can flick, Skee-Ball-style. It may sound absurd, but when you see an onslaught of cubes clopping toward you like so many zombies, don't be surprised if your pulse starts to quicken.
